A method and apparatus of marking livestock, objects and surfaces comprising: selecting a marker cartridge containing a marking means of a selected type, colour or design; securely engaging the marker cartridge into a marker cartridge receiver; attaching the cartridge receiver to a user's wrist with a strap; and marking livestock, objects and surfaces with the selected marking means in the marker cartridge.

What we do claim and desire to obtain by Letters Patent of the United States is: 
     
       1. A marking device for attachment to a user's wrist or other appendage, comprising: (a) a cartridge receiver having a receptacle and a lower outer part;   (b) a marker cartridge having a container for holding a marker means, the marker cartridge and the cartridge receiver having twist-lock means for securely engaging the marker cartridge in the receptacle of the cartridge receiver; and   (c) at least one strap attachment means connected to the lower outer part.   
     
     
       2. A marking device according to claim 1 wherein the receptacle is cylindrical and the receptacle has at least a partial base at a lower inner part. 
     
     
       3. A marking device according to claim 2 wherein the partial base has a central orifice to permit access to the marker cartridge when in place in the cartridge receiver. 
     
     
       4. A marking device according to claim 1 wherein the container has securing means for securing the marking means. 
     
     
       5. A marking device according to claim 4 wherein the container is cylindrical and the container has a base plate comprising a base, side walls and a hollow centre. 
     
     
       6. A marking device according to claim 5 wherein the base plate is removable, and when inserted into the container it forms a friction fit and is capable of being forced up or down the container by the application of pressure to the base plate, movement of the base plate adjusting the level of any contents of the container. 
     
     
       7. A marking device according to claim 4 wherein the marker cartridge further includes a base having a side wall, the side wall having a recess, and wherein the marking means has a ridge of a form complementing the recess, wherein the securing means includes the cooperating relationship between the recess and the ridge. 
     
     
       8. A marking device according to claim 1 wherein the marking means is a wax marker. 
     
     
       9. A marking device according to claim 1 wherein the marker cartridge has an upper part, and wherein a removable seal covers the upper part. 
     
     
       10. A marking device according to claim 1 further comprising at least one strap attached to the marker cartridge receiver, adapted to hold the marking device to a wrist of a user. 
     
     
       11. A marking device according to claim 1 wherein the marker cartridge further includes at least one flange and the cartridge receiver further includes at least one element constructed and arranged to cooperate with the at least one flange, said twist-lock means being formed by twisting the marker cartridge with respect to the cartridge receiver and engaging the at least one element with the at least one flange. 
     
     
       12. A method of marking stock comprising: selecting a marker cartridge containing a marking means of a selected type, colour or design;   securely engaging the marker cartridge into a cartridge receiver;   attaching the cartridge receiver to a user's wrist or other appendage with a strap; and marking stock or any item with the selected marking means in the marker cartridge.   
     
     
       13. A marking device, comprising: (a) a cartridge receiver having a receptacle and a lower outer part;   (b) a marker cartridge comprising a container and a removable base plate, the marker cartridge and the cartridge receiver having interlocking means for securely engaging the marker cartridge in the receptacle of the cartridge receiver, a marking means within the container being secured to the base plate, the base plate forming a friction fit within the container and moving upon the application of pressure to the base plate; and   (c) at least one strap attachment means connected to the lower outer part.   
     
     
       14. A marking device for attachment to a user's wrist or other appendage, comprising: (a) a cartridge receiver having a receptacle, a lower outer part, and a base, the base having an orifice;   (b) a marker cartridge comprising a container for holding a marker means, the marker cartridge being engaged in the receptacle of the cartridge receiver; and   (c) at least one strap attachment means connected to the lower outer part, wherein the orifice within the base permits access to the marker cartridge when the marker cartridge is engaged in the receptacle.
